We’ll go from Philadelphia to Newark - where we found a cheaper direct flight using STA Travel - and then get a direct flight to London. We leave at 8 A.M. and arrive at 8 P.M. - a six-hour flight, with a six-hour time difference.

The ticket itself is $134, but then nearly $180 in taxes, surcharges and fees. Using STA Travel, we saved an additional $100 with a student price.
